LOCOMOTIVE srnuo'ruan.

Application filed August 18, 1926.

My invention relates to railway rolling stock and consists in an improved locomotive bed structure particularly adapted to be used in a locomotive which includes an internal combustion engine utilized to drivethe locomotive by means of electric current or hydraulic pressure.

One object of my invention is to provide an inte ral construction of the locomotive bed and crank case of the engine mounted thereon, whereby the engine may occupy a lower position relative to the bed than heretofore and whereby the crank case may be' :through which the locomotive driving wheels are operated.

These and other detailed objects of my invention are obtained by the structure illustrated in the accompanying drawings forming a part of the specification, in

' which Figure 1 is a side elevation of my improved structure.

Figure 2'is a one-half longitudinal top view of the bed.

Figure 3 isa vertical transverse section taken on line 33 of Figure 1.

Figure 4 is a one-half vertical transverse section taken on line t4 of Figure 1.

The bed proper comprises longitudinal sills 1 preferably formed of box cross section and having recesses at intervals where: by pedestal forming portions 2 are provided for the driving wheels 3.

At the ends of the bed the depth of sills l'may be decreased as the vertical loads are not as great at these points and the sills 1 merge with end sills 4 there being integral elements?) formed with the end sills for mounting the draft element 6. Suitable di Serial No. 129,834.

agonal braces 7 connect the ends of end sills l with the longitudinal sills 1 at points spac odfrom the end sills.

Throughout a substantial portion of the length of the underframe the sills 1 are connected by a transverse web 8 which is curved downwardly from each sill toward the center of the bed and forms the lower portion of the crank case of an internal combustion engine. The central portion of transverse member 8 is preferably depressed as incli- Vcated at 9 to provide a sump for collecting sediment and draining the oil from the crank case. At intervals vertical transverse webs l0 connect sills 1 and have formed in their upper edges integral bearing elements 11 for the engine crank shaft 12. The upper portion 13 of the crank case and the cylinder block'l l are also preferably formed integral with sills 1 although if desired these parts may be made separately and joined to the s lls 1, the upper faces of the latter being machined accordingly.

At the right hand end of the internal combustion engine E, I show a compressor C 'mounted on thesills 1 which are provided with suitable finished bosses 15 for the compressor bracket 16 and to the right of the compressor C the sills l are depressed as indicated at 17 to form a lowered mounting for the reduction gear housing H01 for other apparatus such, for instance, as a generator or motor which would be used in an electric locomotive. The portion of each sill below the housing H may be reduced indepth because this part of the sill is not recessed to form pedestals for the drivers. These parts of the sills are provided with lateralextensions 18 which provide bearings for a ack shaft 19 extending transversely of the bed through openings in sills 1 and mounting gears 20 on its outer ends. These gears are driven by pinions 21 journaled on the housing H and driven by the mechanism contained therein. The gears 20 are connected tothe driving wheels 3 by the connecting rods 22 and the outwardly extending brackets 18 provide bearings for the jack shaft in the plane of the driving wheels and shorten the leverage on the jack shaft.

Preferably the lower portions of the sills .1 are provided with integral brackets 23 I 129,935, each directed to locomotive structures in which the beds or underframes have elements of the driving mechanism formed integrally herewith.

I claim:

1. A one piece casting forming a locomotive bed and including parallel sills, and an engine crank case member extending be tween said sills and forming a longitudinal and transverse brace therefore below the tops of said sills.

2. A one piece casting forming a locomotive bed and including parallel sills, and an engine crank case member extending between said sills and forming a brace therefore below the tops of said sills, said member having an oil sump integral therewith.
